| K40.20 | Bilateral inguinal hernia, without obstruction or gangrene | Use when both inguinal hernias are present without signs of obstruction or gangrene. |
|
| K40.00 | Bilateral inguinal hernia, with obstruction | Use when both hernias are obstructed, confirmed by clinical and imaging findings. |
|
| K40.40 | Bilateral inguinal hernia, with gangrene | Use when gangrene is present in both hernias, confirmed by clinical and surgical findings. |

Primary ICD-10-CM Codes for bilateral inguinal hernia
Decision Criteria
clinical Criteria
- No signs of obstruction or gangrene on examination or imaging.
Applicable To
- Bilateral inguinal hernia without obstruction
- Bilateral inguinal hernia without gangrene
Excludes
- Unilateral inguinal hernia (K40.90)
Clinical Validation Requirements
- Physical exam confirming bilateral reducible masses
- Imaging (e.g., ultrasound) showing no obstruction
Code-Specific Risks
- Misclassification if obstruction or gangrene is present but not documented.
Coding Notes
- Ensure documentation specifies 'bilateral' and absence of obstruction or gangrene.
K40.00 - Bilateral inguinal hernia, with obstruction
Use when both hernias are obstructed, confirmed by clinical and imaging findings.
Applicable To
- Bilateral inguinal hernia with bowel obstruction
Excludes
- Bilateral inguinal hernia without obstruction (K40.20)
Clinical Validation Requirements
- Imaging showing bowel obstruction
- Symptoms such as vomiting or irreducible mass
Coding Notes
Document obstruction clearly with imaging and clinical symptoms.
K40.40 - Bilateral inguinal hernia, with gangrene
Use when gangrene is present in both hernias, confirmed by clinical and surgical findings.
Applicable To
- Bilateral inguinal hernia with gangrene
Excludes
- Bilateral inguinal hernia without gangrene (K40.20)
Clinical Validation Requirements
- Intraoperative findings of necrotic tissue
- Systemic signs such as fever or leukocytosis
Coding Notes
Ensure gangrene is documented with clinical and surgical evidence.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Bilateral Inguinal Hernia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K40.20.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials or reduced reimbursement.
Mitigation Strategy
Thoroughly document clinical findings and imaging results., Use templates to ensure all elements are covered.
Impact
Reimbursement: Incorrect coding can lead to claim denials or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records and data reporting.
Mitigation Strategy
Verify laterality in documentation and use bilateral codes when both sides are affected.
Impact
Incorrect use of modifiers for bilateral procedures can trigger audits.
Mitigation Strategy
Ensure documentation supports the use of modifier -50.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
